UNITED STATES PATENT orrica RICHARD R. .IBLOSS AND SYLVESTEB 1B. CREAMEB, OF COLUMBUS, OHIO, ASSIGNORS TO INTERNATIONAL DERRICK & EQUIPMENT COMPANY, OF COLUMBUS, OHIO, A COR- IE'OBA'IION OF OHIO METAL SHEETING Application filed November 4, 1927. Serial No. 230,991.

Our invention relates to metal sheeting and has to do with the provision of a novel form of sheeting and a novel method of and apparatus for attaching such sheeting to the framework of a building or other structure.

We have provided a sheeting structure made up of separate sheets of such cross-sectional design that a roof or other surface formed from a plurality of such sheets will be capable of carrying a greater load per strong if not stronger than any other part of such sheets.

Our sheeting is so constructed that it ispossible to nest or lap the sheets wlth suflicient exactness to prevent leakage, under any circumstances, without the necessity of special flashing or the use of closing devices at the end laps. Also, our sheeting is constructed so that the separate sheets may be attached together at as many points as is desirable,

' while the attaching mechanism is of a naavoids the use of fastening means, such as.

ture that will permit the sheeting to be taken apart and removed at any time without difliculty or injury to the sheeting.

The attaching mechanism for such sheeting nails or the like, that perforate the metal and is of such nature that the fastening means can be caused to grip and even indent the sheet so as to obviate slippage of the fastening means and of the sheeting as well. The respective sheets have their edges so constructed and the fastening means are so formed complementally, as to prevent any lateral movement of the separate sheets after they are secured together by the fastening means and the fastening means are inherently constructed so as to prevent any possibility of vertlcal or lateral movement of the fastening means itself.

Our invention is fully set forth in the following detailed descri tion and is illustrated in the accompanying rawings wherein similar characters of reference designate corresponding parts and wherein:

Fi re 12 is a side view of the joint shown in Figure 11 showing the securing clampin both inoperative and securing position.

With reference to the drawings, we have shown the preferred form of our invention as embodgmg separate sheets 1. These sheets may be 0 any desired and shape but are,

' preferably, rectangular and may be provided a gutter 2 with one or more ribs or corrugations intermediate the opposite edges of each sheet. The opposite edges of each of the separate sheets are turned upwardly and downwardly to form a rib 2 and then upwardly to form A cap strip 3 is .provided to cooperate with the suitably spaced edges of adjacent sheets and each cap strip is preferably provided with leg portions 4 and angular portions 5 which are adapted to fit the similarly shaped edges of the sheets. The cap strips 3 may be of any desired crosssectional shape and different shapes are shown in Figures 1 and 9.

To secure the cap strip in position after it has been assembled with the adjacent edges of two separate sheets, an H-shaped clamp 6 is provided and, as clearly shown inFigure 1, the projecting portions 7 thereof hook over the tops of the angular portions 5 of the cap strip .and hold them in nested relation with v the ribs 2 at the same time the projecting the sheets. It will be noted that the bottoms portion 8 of the clamp engages the bottoms of the sheets of the gutter 2 of the adjacent sheets 1. As clearly shown in Figure 2, the clamp 6 may be crimped or bent as at 9, so

projecting that the portions 7 and 8 thereof will indent the metal and tightly secure the sheets in position.

This method of securing the sheets together obviates the necessity for punching indexed holes in the sheeting and in the cap strip and provides a rigid assembly, at the same tlme permltting the sheets to be readily disassembled without difficulty or damage to of the gutters 2 of the sheets 1 are in the same plane as the body of the sheets and, therefore, support part of the weight which would, otherwise, be supported by the intermediate part of the sheet.

With reference to Figure 3 of the drawngs, I have shown a modified form of securing clamp 10 wherein the lower projecting portion 11 of the securing clamp is provided with laterally extending portions 12. The purpose of these extending portions is shown n Flgure 4. With reference to this figure, it will be apparent that, when the securing clamp 10 is bent as at 13, the laterally extending portions 12v will be moved upwardly gutters 2 bearing against the opposite sides of thesecuring clamp 10 at the shank thereof, together with the upper projecting portion 14 contacting with the upper part of the angular portions 5 of the cap strip, will obviate any possibility of lateral movement of the separate sheets after they have been assembled with the cap strips and securing clamp.

Referring to Figure 5, we have shown another modification of our securing clamp. In this figure, the lower projecting portion 15 on the securing clamp 16 has the portions 17 thereon which extend outwardly from the top thereof. These outwardly extending portions are adapted to engage the outer sides of the respective gutters 2 of the sheets 1 when the securing clamp is bent as shown in Figure 6, and serve the same purpose as the outwardly extending portions 12 hereinbefore described.

Some of the securing clamps may be constructed in the manner shown in Figure 7 wherein the clamp 18 is provided, with an extension 19 which may be secured to the sup porting framework or purlin in any desired manner and serves to hold the sheets in proper position with relation to such supporting framework or purlin. As shown in Figure 8, the extending portion 19 of the securing clamp 18 is bent around the purlin 20 in such a manner as to hold the sheets securely to the purlin and to prevent,vertical or longitudinal movement of the sheets.

In Figure 9 of the drawings, we have shown a modified form of cap strip in which the legs 21 do not take the same angular shape as the opposite edges of the sheets. Such structure is provided in order that the cap strips may be added after the sheets are assembled if desired. In this instance, the first upward extension of the sheets 1 are used as a flashing to prevent leakage through the joints. If, in this instance, there should be any leakage between the cap strip and the sheets, as a re sult of capillary attraction, the water which has leaked through will be carried away by the gutters 2 along the adjacent edges of the sheets. It will be clearly understood that the leakage, due to capillary attraction, will seldom, if ever, reach such a degree that the gutters 2 will not be able to carry away the water with ease. The gutters 2 are found in all of the structures and serve the same purpose therein.

In Figure 11 of the drawings, we have shown a joint between adjacent edges of separate sheets as being formed without the use of a cap strip. Such construction is seldom used but when it isused, the downwardly depending portions 23 of the upper projecting portion 7 on the securing clamp 6 will prevent lateral movement of the sheets by engaging the first upwardly extending portion of the sheets.

From the preceding description it will be apparent. that we have provided a metal sheeting which maybe adapted to innumerable' uses and which is so constructed that 1t may be quickly and easily applied with the use of simple tools, such as pliers or the like, to form a substantial structure which may be readily disassembled without injury to the sheeting. It will also be apparent that we have provided a sheeting structure in which the selparate sheets will be held securely against ateral movement after they have been assembled. Furthermore, the joints between the sheets are so constructed as to provide a means for carrying away an .water that might possibly seep through t e joints as a result of capillary attraction and obviate the necessity of special flashing.

Having thus described our invention, what we claim is: v 1. A fastening device for the adjacent edges of panels comprising a shank laterally extending hook-like wings on said shank, laterally extending wings spaced therefrom, said last named wings having flange members so constructed and mounted to'prevent' lateral movement of adjacent panels when said shank is bent. v

2. A fastening device for sheeting comprising a body portion, laterally extending wings, and portions extending outwardly in angular relation. to said wings, said por tions being constructed and located to prevent lateral movement of-the sheeting when the fas tening device is bent. i 80 In testimony whereof we herewith aflix our signatures.
